    ATI Radeon X1900 XT PowerPC G5 Leopard Issues
    I have a Power Mac G5 2Ghz (not a Mac Pro) with an ATI Radeon X1900 XT in addition to the original NVIDIA GeForce 6600LE graphics card. All was wonderful, until I installed Leopard. Then any monitor connected to the ATI was showing thin blue horizontal lines and the machine locked up the screen saver kicked in. It would also lock up when dragging an application to or from the ATI connected monitor. I opened tickets with both AMI and Apple, and they both point fingers at each other. I've cleaned the card several times and the latest AMI drivers have been installed, to no avail.

    I do not want to back off of Leopard if at all possible. Has anyone experienced these issues and if so is there a resolution?

    When owned a Dual Core G5 had this problem. Is the card a flashed PC card or the Radeon X1900GT? The flashed card caused precisely the problems you describe whereas a specific Mac card did not.
